Study on Charging Method with Electric Vehicle Plug-in Distributed Network of Residential District

摘要

Based on the analysis of driving characteristic of electric vehicle, the charging load probability distribution model is established. Then taking into account the interests of power grid and users, a multi-objective optimization control methods of residential electric vehicle charging is presented. It can make electric vehicles access to residential power system directly, without increasing the distribution capacity. At the same time, the peak load, the peak valley difference and the charging cost can be achieved by comprehensive optimization. Finally, an example of a typical district demonstrates the feasibility and economics of electric vehicle plug-in residential district distributed network.
